COMBINED WASHING MACHINE AND DRIER Application led October 8, 1927. Serial No. 224,780.

i general domestic use in which a drying and a washing operation may be performed in a single .tank concurrently. A further' object is to dry the laundry by centrifugal force and eliminate the danger to both the user and the laundry by the wringer mechanisms now commonly employed. A further object is to provide a washing machine in which the laundry during the-washing process is retained in a looseI condition and carried l'in/ a continuous path Aby the wash water, thereby preventing matting, and enabling the ready loosening of dirt from the laundry. Still a further object is to eliminate any moving parts which, contacting with delicate garments, may injure the same. An-

other object is to 4provide a washer in which the cleansing is performed entirely by the action of currents of water containing the desired cleansing agent, such as soap. A

s lfurther object is to provide a machine W 'ch has a minimum of rotating parts and thereby a machine which is extremely simple and not likely to require adjustment, or repairs.

Fig. 4 is asection of this machine along the line 4 4 of Fig. 3 showing th parts in elevation.

Fig. 5 is an enlarged view of the drier mounting in section of the machine of Fig. v3, and Fig. 6 is a partial view of the tank of this machineA showing the agitator and agitator casing in section;

Reference being had to the drawings, the cylindrical tank, 10, is supported upon a 50. convenient structure, 11. Amotor, 12, is affixed to the supporting structure and belowv the tank, carrying a pulley, 23, and ,driving by means of a belt, 24, the pulley, 22, upon t e centrifugal driershaft, 21.

The tank, 10, is divided into two .compartments b means of the partition, 15, one of which receive the laundry to be washed, Whereas in the other compartment, 26 the centrifugal drierv mechanism, 14, is disposed. The partition is S shaped, or any Iother convenient curved shape to give the wash water a continuous current .path `without abrupt breaks or bends. The partition is perforated,.h17, below the water line .and at the end remote from the orice, 39 shown in' Figs. 1, 3 and 6.

The centrifugal drier. is formed in the shape of a hollow inverted cone having an inwardly projecting rim, 18, at the top. Immediately below this rim and above the water level of the machine, a series of openings, 19, are provided permitting the draining of the water extracted from the laundry which is being dried back into the tank. On the outer surface of the rotating container are a convenient number of vanes, 16, projecting from the portion of the centaine!I submerged in the wash water and serving to give it a continuous current, as indicated by the arrows in Fig. 1. The rotating container, 14, is rigidly mounted upon and supported by the collar, 27, keyed to the shaft, 21. The closure member, 28, is welded or riveted to the bottom of the tank and is in tegral with the shaft bearing, 29. The lower end thereof is conveniently threaded and compartments is adapted to packing provided therebetween and the nut, 30, conveniently .made of a size to be tightened by hand. 4 y n In a variation of my invention, shown 1n Figs. 3, 4 and v5, the centrifugal drier is formed with a re-entrant base, 31, with its central portion extending upwardly to above the Water line. This re-entrant -portion is rotatably` supported upon and by the upi wardly pro]ecting portion, 32, of the agitator, 33. The agitator is Xed to the shaft, near its upper end and rotates therewith. The lower end, 34, is rotatably supported upon the sleeve, 35, wh'ch extends through` obtained .while another batch the base of the tank an into the compartment, 26. A clutching device, 36, is provided at the extreme u per end and threaded end of the shaft, tlie stop, 37, limiting the upward movement of the clutching knob, 36.

The agitator' blades, 33,. are suitably housed in a casing, 38, at the bottom of the centrifugal drier compartment and are designed to discharge the water through the orifice, 39. The circular opening, 40, in the a -tator casing at the top thereof permits t e continuous use of the water in the tank.

In the operation of lthe machine, the tank is filled with water to ailevel below the perforations, 19, in the combined drier and agitator. The batch of laundry to be washed is placed inthe washing compartment and thereupon the motor is started. The container, 14, wi agitate or impel the water by means of varies 16, causing a circulation of the water in the direction of the arrows shown in Figs. 1 and 3. t the same time any laundr which has been ashed in a previous batc and which has been ut into the container, 14, is whirled aroun at a speed suicient to drive the water upwardlyv along the sides of the container and t ro h the rforations, 19, drainin back into t e was water in the tank. hus a simultaneous drying of the clothes may be is being washed.

In the alternative arrangement if there is no laundry to be dried in the centrifu al drier the clutch, 36, is given a few turns y hand thus releasing it from the reentrant portion, 31, of the container. Upon starting the motor the clutch and shaft as well as the agitator will rotate while the drier remains stationary. Thereafter for the washing of the second and subsequent batches of laundry, the clutch is,given a few turns in the o posite direction and the container is c utclied to the shaft and whirled around therewith at a speed suilcient to extract the wafer from the clothes.

Whatisclaimedis:
